http://kb.parallels.com/en/116992 For those people who are experiencing too many issues to continue using Parallels 9. I personally am downgrading to 8, which is still available for download on the Parallels home page.
Well, these instructions are incomplete. They do not install the (virus) Parallels Access. The menu daemon starts up when the machine starts up and cannot be removed by going to System Preference and disabling it from the Login Items. It's not there! So, you can't completely uninstall Parallels 9. Not yet at least.
